Tests: Enhance robustness of stdout driven waiting state in Sikuli based tests.
Some tests were randomly passing, because from time to time waiting for idle was skiped. It was combination of multiple problems :
- buffering on stdout (now use readline + flush for each write to log)
- it is sometime required to wait for activity before waiting for timeout added "WaitForChangeAndIdle" to "stdoutIdleObserver"

Meter widget moves the end of "needle" labeled path along "range" labeled
path, according to value of the single accepted variable.
Needle is reduced to a single segment. If "min" a "max" labeled texts
are provided, or if first and second argument are given, then they are used
as respective minimum and maximum value. Otherwise, value is expected to be
in between 0 and 100.
